No. 29/393,079, filed May31, 2011, now U.S. Pat. No.: D668,401, issued Oct. 2, 2012, incorporatedherein by reference in its entirety.

BACKGROUND OF THE INVENTION

A dishwasher removes unwanted foreign substances from reusable crockeryand utensils using washing liquid injected through an injection nozzle.The nozzle may be located in various locations inside the dishwasher,e.g., typically directly beneath the dishes, or, in the case of U.S.Pat. No. 3,167,183, may be located beside the dishes. The removedsubstances then drop to the bottom of a tub beneath the dishes.

Typically, a dishwasher contains at least one crockery basket or rack,usually two, each with a number of upstanding tines to hold the crockeryin an upright position to allow for maximum cleaning. Occasionally, asshown in U.S. Pat. No. 7,793,790 B2, dishwashers will contain a bottlerack for separately placing dishware products having a hollow shape,such as milk bottles and feeding bottles, in a vertical position tomaximize cleaning. As shown in U.S. Pat. No. 4,927,033, an articleholder for the dish rack of a dishwasher is provided for securelyholding cup shaped articles in an upright position on the sides of thebasket. In U.S. Pat. No. 2,655,267 a detachable device to prevent damageto glasses and cups from heavier metal instruments by more forcefullysupporting the objects is disclosed. U.S. Pat. No. 4,593,822 disclosesan arrangement to prevent damage to dishware due to the deterioration ofcoatings of a wire rack due to continued exposure to high levels of heatby introducing a removable and replaceable sleeve. As shown in U.S. Pat.No. 2,841,288, plates are occasionally held in place by tilted racks onboth sides and with raised lower supports extending from one tilted rackto the other, and also holding the dish. In addition to dishes, specifictypes of reusable bags can also be washed in dishwashers, using thespecial dishwasher attachment shown in U.S. Pat. No. 5,405,018. Alsoknown is an accessory which may be clamped in an upright manner to anexisting basket, to hold a baby bottle.

A need has developed to address one or more shortcomings of the priorart.

BRIEF SUMMARY OF THE INVENTION

One aspect of the present technology is directed to a dishwasheraccessory to hold or help hold in place various items of crockery tomaximize the support given to these items to help prevent them fromfalling over and/or being cleaned improperly.

In one example, a dishwasher accessory may be removably secured to arack of the dishwasher in such a way as to blend with the existingstructure of the rack, in a space conserving manner. For example, thedishwasher accessory may have a main body with a distal end that isaligned with the tines, but extends to a height that is greater than theheight of the tine.

In one example, a dishwasher accessory is attachable to one or moreexisting tines of a dishwasher, e.g., by providing the accessory withhollow ends than can be slid over the existing tines.

The accessory may have a predefined shape, or it may be deformable,e.g., in one of three ways: elastically, plastically or in a pluralityof predetermined positions, similar to how a drinking straw withcorrugations is adjustable.

In another example of the present technology, there is provided anaccessory for supporting crockery in a dishwasher, the accessorycomprising a generally U-shaped main body having a pair of legs and aconnecting portion that connects the pair of legs, at least one of thelegs having a free end that is adapted to be releasably attached to acrockery basket in the dishwasher when in an installation position, anda smoothly or gently radiused portion connecting each leg to theconnecting portion, wherein the legs are spaced apart in theinstallation position a sufficient distance to promote stability of thecrockery. The sufficient distance maybe about 4-15 cm, or about 8-12 orabout 5-8 cm, or at least 4 cm.

In another example of the present technology, there is provided anaccessory for a dishwasher having at least one crockery basket with abase and upstanding tines extending at an angle relative to the base,said accessory comprising a main body having a proximal end forconnection to the crockery basket, and a distal end extending away fromthe proximal end, e.g., in cantilever fashion, wherein the distal end isangled to match the angle at which the upstanding tines of the crockerybasket are oriented and dimensioned to extend a height that is greaterthan the height of the tines.

In another example of the present technology, there is provided anaccessory for a dishwasher for washing crockery, the dishwasher havingat least one crockery basket, said accessory comprising a main bodyhaving a proximal end for connection to the crockery basket, and adistal end extending away from the proximal end in cantilever fashion,wherein the main body, e.g., distal end, is adjustable in dependence onshape and/or size of the crockery.

These and other aspects of the present technology will be described inor apparent from the following detailed description.

DETAILED DESCRIPTION

The present technology is described in relation to several examples thatmay share one or more common features. It should be noted that an aspectof one example can be combined with an aspect of another example, andthat any aspect of any example may form the basis for subject matterapplicant may wish to pursue.

FIG. 1 is a schematic view of a dishwasher 5 for washing and/or dryingcrockery items, such as dishes, frying pans, cookie sheets, cuttingboards, bowls, pots, etc. Dishwasher 5 includes a manually openable door10 and a compartment 15. Door 10 is openable to allow access to thecompartment 15. Door 10 will form a generally water/air tight sealrelative to the compartment 15 when closed. The compartment 15 includesat least one crockery basket 20, 25.

FIG. 2 shows further details of a portion of the sample crockery basket25, within which are several rows of generally parallel base rails 27and upright tines 30, generally used to support the items of crockery tomaximize cleaning efficiency. However, sometimes the existing tines 30are not enough to fully and/or optimally stabilize larger and/orirregular items, in a space conserving manner, in which case such itemsmay not be fully washed/rinsed, or they may impact the loading/cleaningefficiency of surrounding items. There are several different designs forthe dishwasher accessories, and each one may be specifically designed tosupport a different type of crockery item, or they may be adjustable.

FIGS. 2 through 8 show a first example of a dishwasher accessory 45 ofthe present technology. The dishwasher accessory 45 attaches or isotherwise provided to the crockery basket 20, in an easily removablemanner. Dishwasher accessory 45 can be provided to the base rail 27,existing tines 30, or even sides of the basket 25.

As shown in FIG. 2, accessory 45 has a main body 46, a proximal end 50that is attached to the basket and a distal end 55 that extends awayfrom the distal end 50. The accessory 45 may have a generally U-shape,including a pair of legs 60 and a connecting portion 56 (FIG. 4)although other shapes are contemplated. The U-shape is able to betterfit the contour of dishes and other crockery and avoids the potentialfor sharp points (e.g., from existing tines) that may cause damage tothe crockery and/or premature wear on the accessory itself, which may bea malleable wire coated with a soft layer, e.g., plastic, etc.

The spacing between the legs may be about 4-15 cm, e.g., 5-8 cm, or 8-12cm (or roughly about 95 mm) to ensure adequate contact with thecrockery, and/or to best ensure stability of the crockery in an uprightor optimal cleaning position that can robustly withstand the variouscleaning/rinsing cycles which occur in a dishwasher. If the distancebetween the legs is less than 4 cm, then the stability of the crockerymay be compromised, and if the distance is greater than about 15 cm,then the accessory will be wider than a large percentage of the crockerythat is intended to be supported by the accessory.

The U-shape may also include smooth, radiused transitions 57 (FIG. 4)between the legs 60 of the U-shape and the connecting portion 56 ordistal end 55 of the U-shape, to enhance stable support. The distal end55 and/or the radiused transitions 57 are intended to support thecrockery.

Each leg 60 of the U shape may include an attaching member for attachingto the base rails 27 of the basket 25. In FIG. 2, each end of the legs60 includes an attaching member in the form of a claw 65, one attachedor otherwise provided to each leg 60 of the accessory. Each claw 65includes a cross member 70 and at least one hook member 75, with twosuch hook members for each claw 65 being shown in the example of FIG. 2.The hook members 75 are spaced to provide sufficient stability.

FIGS. 2 and 3 show the accessory 45 in the attached or installationposition relative to the basket 25. As shown in FIG. 3, the angle of themain body 46 is selected to match the angle of the existing tines 30(part of the accessory 45 is hidden behind the tine 30), which helps toensure that the accessory blends 45 with the basket 25, to help maintainmaximum loading capacity and cleaning efficiency. The main body 46,e.g., the distal and/or proximal ends 50, 55 of the accessory 45 can beadjustable relative to the cross member 70, e.g., by using deformablematerials such as malleable wires, to allow the angle of tines to bematched.

FIG. 3 shows the distal end 55 of the accessory 45 to extend an exposedheight h that is greater than the height of the tines 30, e.g., in therange of about 5-10 cm. The accessory has an overall height ofapproximately 10-20 cm.

While FIGS. 2 and 3 show the accessory in the attached or installationposition, FIG. 4 shows the accessory in the pre-attached,pre-installation position. As shown in FIG. 4, the legs 60 are pulledoutwards from both sides in the directions indicated by the arrows untilthe distance 76 between the claws 65, and more particularly the tips ofthe hooks 75, is more than the distance 77 (FIG. 2) between the baserails 27. Once the legs 60 are stretched to achieve this distance, theyare released at which point the resiliency of the legs causes the hooks75 to “snap” in and firmly engage the respective rails 27. It can beappreciated that the legs 60 in FIG. 4 converge towards one another asseen in the direction of the proximal end 50 of the accessory 45, butthe legs 60 are generally parallel once the accessory 45 takes up theattached position (FIG. 2).

FIG. 4 shows that the hook 75 is formed at an angle α relative to thecross member 70 of the claw 65. FIG. 8 shows the accessory 45 from thefront, making more apparent the angle α between the cross 75 and thehook 80 that makes supporting larger crockery easier. The angle α is inthe range of 5-45 degrees, or about 10-30 degrees.

FIG. 5 shows the accessory in side view, including the angle β that isbetween the proximal end 50 and the cross member 70. Angle β is in therange of about 45 to less than 90 degrees or about 60-75 degrees. Theangles α and β may be adjustable, e.g., by making the accessory ofspring wire that can be deformed.

Adjustability may be provided in the form of an adjustment mechanism,e.g., to allow selection of two or more predetermined positions, e.g.,like corrugations in a drinking straw may allow the tip of the straw toassume a number of positions. As seen in FIGS. 6 and 7, the angle β mayresult in the distal end 55 of the accessory being positioned slightlyoutward of an extent 73 between the hooks 75. Although the distal end 55is shown to project a small distance 71 (e.g., of a few millimeters,e.g., 1-10 mm) outside one of the hooks 75, the distal end 55 may bepositioned within the extent 73 and between the claws as seen in FIGS. 6and 7. Such configuration helps to provide stability (given the distancebetween the hooks) and at the same time allow the angle β to match theangle of the tines in the basket.

FIGS. 9 through 13 show a second example of a dishwasher accessory 200according to the present technology. Accessory 200 is similar toaccessory 45 and thus parts that operate in the same manner will not berepeated for the sake of conciseness, where like reference numbersindicate like parts. Accessory 200 differs from accessory 45 in avariant on the way that it can be attached to the crockery basket's baserails 27. As shown in FIG. 9, the claws 265 are rotated 90° compared tothe claws 65 shown in FIGS. 2-8. The claws 265 may be fixedly attachedin this manner, or they can be adjustable via an adjustment mechanism,e.g., the proximal end 250 may be swivelable or rotatable relative tothe cross member 270. When in this position, the claws 265 can besqueezed in the direction indicated by the arrows against the naturalresiliency of opposed legs 260 of the accessory, which again has agenerally U-shape. This is in contrast to the pulling the legs outwardsin relation to accessory 45.

FIG. 10 features the accessory 200 in a relaxed, pre-installationposition (solid lines) as well as in the installation position (brokenlines). Again, the legs 260 are generally parallel to one another in theinstallation position, and generally not parallel (diverging away fromone another in the direction of the proximal ends 250) in thepre-installation position. As compared to accessory 45, a distance 266between the claws may be less than the distance 76 between the claws asshown in FIG. 4, which distance may be more useful if the base rails 27of the basket 25 are closer to one another.

As shown in FIG. 14, an accessory 290 can also be manufactured of amaterial (e.g., spring wire) that that allows the claws 65, 265 to bepositioned in either the inwardly facing orientation (FIGS. 2-8) oralternatively the outwardly facing orientation (FIGS. 9-13). FIG. 14shows the inwardly facing orientation in the broken lines, which can beconverted into the solid line orientation by bending one leg 60, 260over the distal end as indicated by the arrow until the claws 65, 265face away from one another.

FIGS. 15 and 16 show another example of an accessory 300 according tothe present technology. Accessory 300 is similar to accessory 45, buthas an exposed height H, i.e., the amount it rises above the tines 30,that is greater than the exposed height h shown in FIG. 3 in relation toaccessory 45. The greater height H allows for better and/or morecomplete support of even taller pieces of crockery, e.g., cookie sheets.The exposed height H is approximately 10-15 cm.

FIG. 16 also shows that the claw 365 to have a slightly different shape.Specifically, the claw 365 includes a cross member 370 and a hook 375,as above, but the hook 375 is generally radiused rather than beingangled relative to the cross member 370.

FIGS. 17-22 show another variant of an accessory 400 according to thepresent technology. Accessory 400 includes a proximal end 450 and adistal end 455, but the proximal end 450 attaches onto the crockerybasket in a different manner as compared to the examples discussedabove. For example, the accessory 400 is U-shaped and includes first andsecond legs 460, the proximal end of which is connected to the tines 30(FIG. 22). In the specific example shown each end 450 has a hollow tipportion 451 dimensioned to receive the end 30.1 of an existing tine 30of the crockery basket 25. Specifically, the inner diameter d of thehollow tip portion is about equal to, or slightly greater or less than,the diameter D (or cross sectional dimension) of the end 30.1 of tine30. The hollow tip portions 451 may take the form of a blind bore tolimit the insertion depth (e.g., 1-2 cm) of the tines 30 into the hollowtip portions 451 of the accessory 400.

As shown in FIG. 18, accessory 500 has a general “U” shape, with thedistal and proximal ends being in the same general plane, as also shownin FIGS. 19-21. The distal end provides a smooth surface such thatcrockery, e.g., a plate or pan 499 (FIG. 22) with a shallow concavity,can be supported in a position that is more ideal for dishwashingmachines and without scratching and with improved stability.

FIGS. 23-28 show an accessory 500 according to another aspect of thepresent technology. Accessory 500 shares many similarities withaccessory 400. One main difference is that the accessory 500 has a morepronounced three dimensional shape to better support crockery with adeeper bowl area, as shown in FIG. 28. The accessory may have apre-defined shape, or it may start off in a generally planar state as inthe accessory 400 and be bent or shaped to match the general dimensionsor depth of the crockery to be supported, e.g., by plastic deformationand/or by elastic deformation due to the weight of the crockery.

Accessory 500 has a generally U-shape with a pair of legs 560 orproximal portions 550 and a connecting portion 556 or distal portion 555that connects the legs 560 to one another. Legs 560 have hollow tips 551as described above, and begin to curve at a distance 553 that is abouttwo thirds of the total height 554 of the accessory 500. The connectingportion 556 extends at an angle δ that is about 50-80 degrees relativeto the legs 560. This shape helps to support bowls or other deeplyconcave crockery, e.g., pots.

While the accessory shown in FIGS. 23-28 includes hollow ends thatreceive tines of the basket, in an alternative, the accessory 500 may beattached to the basket using an attachment mechanism like those shownand described in relation to FIG. 8 or FIG. 9, e.g., claw likeattachment mechanism.

While the present technology has been described in connection with whatare presently considered to be the most practical and preferredexamples, it is to be understood that the technology is not to belimited to the disclosed examples, but on the contrary, is intended tocover various modifications and equivalent arrangements included withinthe spirit and scope of the disclosure.
